This is no, there is no, modern romance...

The summer is coming to a close, and i'm feeling incomplete. Although its been an amazing ride, i am no longer content with the things happening in my life. I feel trapped and cornered and i am involved in a relationship i think i know in my heart i don't really want anymore. But how can i all of a sudden not want something i have been wanting for so long? And i thought i was content, i really did. and all of sudden i just need out. and i don't know how to handle it. If i change my situation, i'll be hurting someone i care about. And the worst part of it is, people i can't stand knew this would happen. they called that i'm the type of person to do something like this. i hate proving them right. i hate that i feel like if i do this i will be accepting the fact that i am a selfish, heart-eating bitch. so maybe i am. but how long can i sacrifice my happiness for someone else's? and its not even like i'm making him all that happy either. I am moody and unpredictable and sometimes downright mean. i just don't like feeling tied down, and in so many ways he is exactly what i don't want to be involved with. He's needy, and clingy, and so very very public about everything. and if there's anything i can't stand, its someone being public with something i feel should be private. but at the same time, he's sweet and funny and caring.but i guess what it comes down to is that its a lot harder to see him now, and i have to really make it a priority in my life. and i just don't care to. so where does that leave me?
